Date: Fri, 9 Feb 2007 09:31:05 +0100 X-Mailer: Apple Mail (2.752.3) X-Virus-Checked: Checked by ClamAV on apache.org I just woke up thinking it would be cool to attempt reducing the data of all documents using PCA (or so) and store the output in a new field per dimention introduced in order to find similair documents by placing a simple proximity query. Did anyone attempt something like this? I did not think this through that much. Nor do I need this feature. Just think it would be a cool experiment. -- karl --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscribe@lucene.apache.org For additional commands, e-mail: java-user-help@lucene.apache.org
